Description

Technical Field

[0001] This invention belongs to the technical field of spray painting equipment, and in particular relates to an environmentally friendly, safe and efficient spray painting device. Background Technology

[0002] Spray painting is a surface treatment technique that forms a protective or decorative layer by spraying paint into the surface of an object in a mist form. Traditional spray painting operations have the following limitations:

[0003] Traditional spray painting operations typically rely on manual labor or semi-automatic equipment, resulting in low efficiency and failing to meet the demands of modern industrial rapid production. During manual spray painting, human factors such as operator skill level and work condition can easily lead to uneven paint thickness and inconsistent colors, affecting product quality. Furthermore, untreated paint mist released directly into the atmosphere during spray painting can pollute the environment. Long-term exposure to working environments containing harmful substances also poses a threat to operator health. Finally, insufficient precise control over spraying angle, distance, and coating amount makes it difficult to achieve high-quality surface treatment results.

[0004] To address these issues, we provide an environmentally friendly, safe, and efficient painting device. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to an environmentally friendly, safe, and efficient painting device, comprising a base plate, a positioning fixture that moves along the length of the base plate, a painting assembly disposed on the side of the positioning fixture, and a movement detection assembly disposed on the upper part of the positioning fixture. The positioning fixture includes a support plate parallel to the base plate, a vertical plate fixed to the upper side of the support plate, a drive shaft passing through the bottom of the vertical plate, and a positioning frame connected to the end of the drive shaft via a vertical belt drive structure. The painting assembly includes a shaft, a bracket sleeved outside the shaft, a connecting block fixed to the lower part of the bracket, and an air rod fixed to the connecting block. The main body of the air rod is fixed to the shaft, and a paint nozzle is fixed to the front end of the bracket. The paint nozzle is connected to an external feeding device via a hose. The movement detection assembly includes an X-axis linear guide, a Y-axis linear guide mounted on the moving end of the X-axis linear guide, a Z-axis linear guide fixed to the moving end of the Y-axis linear guide, and a vision detector fixed to the moving end of the Z-axis linear guide.

[0007] The present invention is further configured such that a protective component is provided on the upper part of the base plate, the protective component including a machine cover fixed to one upper end of the base plate, a back plate fixed to the rear of the machine cover, a baffle fixed to the front of the machine cover, and a slide rail fixed to the upper side of the base plate, wherein the side of the support plate is slidably disposed in a slide groove opened inside the slide rail.

[0008] The invention is further configured such that the protective component includes a drive motor fixed to the other end of the upper side of the base plate, the output end of the drive motor is connected to a screw, and the other end of the screw is connected to the lower side of the support plate.

[0009] The present invention is further configured such that one end of the transmission shaft is fixed with the output shaft of a rotary motor, and the rotary motor is fixed to the upper side of the support plate.

[0010] The present invention is further configured such that the positioning frame is movably connected to the upper middle position of the vertical plate via a bearing seat, and the workpiece to be painted is fixed between the positioning frames arranged opposite each other.

[0011] The present invention is further configured such that a mounting plate is fixed at the bottom of the X-axis linear guide rail, the mounting plate being fixed inside the machine cover, and an auxiliary guide rail is fixed at the lower end of the Y-axis linear guide rail away from the X-axis linear guide rail, the auxiliary guide rail also being fixed inside the machine cover.

[0012] The invention is further configured such that the cover covers the outside of the positioning fixture and the moving detection component, and the baffle on the front of the cover has an opening for the positioning fixture to enter and exit.

[0013] The invention is further configured such that a rotary drive is fixed on the inner side of the back plate, and the output shaft of the rotary drive is engaged with the end of the shaft via an oblique belt drive structure, and the shaft is movably disposed inside the machine cover.

[0014] The invention is further configured such that an isolation cover is fixed to the outside of the back plate, and the isolation cover is fixed to the outside of the inclined belt drive structure.

[0015] The present invention is further configured such that a pair of rotary drives are connected to an external control system via connecting lines, and the rotary drives operate independently of each other.

[0016] The present invention has the following beneficial effects:

[0017] 1. This invention achieves a fully automated process from workpiece fixing and rotation to painting by setting up automated positioning fixtures and moving detection components, which shortens the processing time of a single workpiece. The three-dimensional moving system composed of X-axis linear guides, Y-axis linear guides and Z-axis linear guides enables the vision detector to move flexibly in all directions, monitor and provide feedback on the painting effect in real time, and ensure precise control in the painting process.

[0018] 2. This invention achieves precise adjustment of the spray nozzle angle by setting up an independently operating rotary drive and inclined belt transmission structure, ensuring that the best spraying effect can be achieved at each angle during the spraying process. The rotary motor drives the positioning frame and the workpiece between them to rotate through the transmission shaft and vertical belt transmission structure, thereby achieving uniform spraying on all sides of the workpiece, which greatly improves the uniformity and coverage of the paint spraying.

[0019] 3. The entire painting process of the painting device provided by the present invention is carried out in a relatively closed machine hood environment, which effectively prevents the spread of paint mist, protects the safety of the working environment, reduces the risk of workers being exposed to harmful substances, and its highly automated process reduces the need for manual intervention and reduces the safety risks caused by human error.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0031] Example

[0032] Please see Figure 1-6 This invention relates to an environmentally friendly, safe, and efficient painting device, comprising a base plate 100, a positioning fixture 300 that moves along the length of the base plate 100, a painting assembly 500 disposed on the side of the positioning fixture 300, and a movement detection assembly 400 disposed on the upper part of the positioning fixture 300. The positioning fixture 300 includes a support plate 301 parallel to the base plate 100, a vertical plate 302 fixed to the upper side of the support plate 301, a drive shaft 303 passing through the bottom of the vertical plate 302, and a positioning frame 305 connected to the end of the drive shaft 303 via a vertical belt drive structure 304. The painting assembly 500 includes a shaft 501 and a painting assembly 400 sleeved on the base plate 100. The shaft 501 has an external bracket 504, a connecting block 503 fixed to the lower part of the bracket 504, and an air rod 502 fixed to the connecting block 503. The main body of the air rod 502 is fixed to the shaft 501. A paint spray nozzle 506 is fixed to the front end of the bracket 504. The paint spray nozzle 506 is connected to an external feeding device via a hose. The moving detection assembly 400 includes an X-axis linear guide 402, a Y-axis linear guide 404 mounted on the moving end of the X-axis linear guide 402, a Z-axis linear guide 405 fixed to the moving end of the Y-axis linear guide 404, and a vision detector 406 fixed to the moving end of the Z-axis linear guide 405.

[0033] Specifically, a protective component 200 is provided on the upper part of the base plate 100. The protective component 200 includes a machine cover 201 fixed to one end of the upper side of the base plate 100, a back plate 202 fixed to the rear of the machine cover 201, a baffle 204 fixed to the front of the machine cover 201, and a slide rail 206 fixed to the upper side of the base plate 100. The support plate 301 is slidably disposed in a groove opened inside the slide rail 206. The base plate 100 provides support for the machine cover 201, and the machine cover 201 provides a protective environment for the painting operation. The slide rail 206 can ensure the stable entry and exit of the positioning fixture 300 into and out of the machine cover 201.

[0034] A rotary drive 505 is fixed to the inner side of the back plate 202. The output shaft of the rotary drive 505 is connected to the end of the shaft 501 via an inclined belt drive structure 507. The shaft 501 is movably disposed inside the cover 201. A pair of rotary drives 505 are connected to an external control system via connecting lines. The rotary drives 505 operate independently of each other. The rotary drive 505 drives the shaft 501 to rotate via the inclined belt drive structure 507, thereby realizing the overall angle adjustment of the bracket 504 and the air spring 502, and finally realizing the adjustment of the spraying angle of the paint nozzle 506.

[0035] Furthermore, the protective assembly 200 also includes a drive motor 205 fixed to the other end of the upper side of the base plate 100. The output end of the drive motor 205 is connected to a screw 207, and the other end of the screw 207 is connected to the lower side of the support plate 301. The drive motor 205 drives the screw 207 to rotate, thereby achieving linear drive of the support plate 301 and controlling the positioning fixture 300 to enter and exit the machine cover 201. The machine cover 201 covers the positioning fixture 300 and the movement detection assembly 400. The machine cover 201 has a baffle 204 on the front for the positioning fixture 300 to enter and exit. An isolation cover 203 is fixed to the outside of the back plate 202. The isolation cover 203 is fixed to the outside of the inclined belt drive structure 507. The machine cover 201 not only provides installation support for the positioning fixture 300 and the moving detection component 400, but also provides a semi-enclosed painting space to prevent air from escaping into the air. At the same time, the dark space provided by the machine cover 201 is more conducive to the detection operation of the vision detector 406.

[0036] In addition, the output shaft of the rotary motor 306 is fixed at one end of the drive shaft 303. The rotary motor 306 is fixed on the upper side of the support plate 301. The positioning frame 305 is movably connected to the upper middle position of the vertical plate 302 via a bearing seat. The workpiece to be painted is fixed between the positioning frames 305 that are arranged opposite each other. The rotary motor 306 provides rotational power to the drive shaft 303. When the drive shaft 303 rotates, it will drive the positioning frame 305 to rotate relative to the support plate 301 through the vertical belt drive structure 304, thereby realizing the flipping of the workpiece.

[0037] The bottom of the X-axis linear guide 402 is fixed with a mounting plate 401, which is fixed inside the housing 201. The lower side of the Y-axis linear guide 404, away from the X-axis linear guide 402, is fixed with an auxiliary guide 403, which is also fixed inside the housing 201. The mounting plate 401 and the auxiliary guide 403 are both fixed inside the housing 201, forming a support layer for the motion detection component 400. At the same time, the auxiliary guide 403 is also used to assist the linear movement of the Y-axis linear guide 404 relative to the X-axis linear guide 402.

[0038] The specific operation steps in this embodiment are as follows:

[0039] When operating this environmentally friendly, safe, and efficient painting device, the workpiece to be painted must first be securely installed between the positioning frames 305 to ensure that the workpiece will not shift or loosen during subsequent rotation and painting, thus guaranteeing the consistency and stability of the painting quality. After the workpiece is fixed, the drive motor 205 drives the screw 207 to rotate, allowing the support plate 301 to move smoothly along the slide rail 206 on the base plate 100, thereby sending the entire positioning fixture 300 along with the workpiece to be painted into the machine hood 201, realizing the entry operation of the positioning fixture 300. To meet the painting requirements at different angles, the angle of the shaft 501 can be precisely adjusted by a pair of independently operating rotary drives 505 via the inclined belt drive structure 507, thereby driving the overall angle change of the bracket 504 and the air rod 502 to achieve the optimal painting position. At the same time, the vision detector 406 uses the X-axis linear guide 40 2. The three-dimensional moving system, composed of the Y-axis linear guide 404 and the Z-axis linear guide 405, moves flexibly within the machine housing 201, monitoring and providing feedback on the painting effect in real time to ensure that every detail meets the expected standards. To achieve all-around painting of the workpiece, the rotary motor 306 can be activated. It drives the positioning frame 305 and the workpiece between them to rotate through the transmission shaft 303 and the vertical belt drive structure 304. This allows for painting operations on different sides of the workpiece, greatly improving work efficiency and the uniformity of the paint spraying. The entire painting process is carried out in a relatively enclosed environment of the machine housing 201, effectively preventing the spread of paint mist and protecting the safety and cleanliness of the working environment. Finally, after the painting is completed, the drive motor 205 is used again to reverse the screw 207, causing the positioning fixture 300 to smoothly exit from the machine housing 201 with the painted workpiece, marking the end of the entire painting process.
